Sudoku features a square puzzle consisting of nine rows and nine columns, which together form nine 3x3 mini-squares within the overall layout. Puzzlers must use numerals 1 through 9 - without repeating - in each row, column and mini-square. Sudoku Sunday Classics are identical to the daily version, specifically the Thursday and Friday versions, which are the most challenging.
